The former Toronto midfielder took advantage of the hosts' inability to clear a deflected cross and poked the ball past goalkeeper Joe Bendik, just minutes after Kansas City captain Matt Besler was sent off in the 76th minute for a second yellow card.

Earlier, Jackson scored for Toronto in the 16th minute, before Graham Zusi equalized for defending MLS champion Kansas City shortly after half time.

Kansas City moved to 38 points on the back of its fourth straight win and sits atop the MLS Eastern Conference.
